Answer: If you want the answer then it is x=4
Step-by-step explanation:
Subtract 6 from both sides
2x=7x-20
subtract 7x on both sides
-5x=-20
Lastly divide both sides by the same term(-5)
x=4
Hope this helps and a brainliest would be appreciated
Pythagoras theorem is c^2 = b^2 + a^2
so when you plug in the numbers its 12^2 + 5^2 =169
which means 144+24=169
square root 169 = 13
AB =13 cm
hope this helps I tried my best. xx
Answer:
It would be 63
Step-by-step explanation:
This is because 9 x 7 = 63
Simple math.
The standard deviation for the number of people with the genetic mutation is 3.77
<h3>How to determine the standard deviation?</h3>
The given parameters are:
Sample size, n = 300
Proportion that has the particular genetic mutation, p = 5%
The standard deviation for the number of people with the genetic mutation is calculated as:
Standard deviation = √np(1 - p)
Substitute the known values in the above equation
Standard deviation = √300 * 5% * (1 - 5%)
Evaluate the product
Standard deviation = √14.25
Evaluate the exponent
Standard deviation = 3.77
Hence, the standard deviation for the number of people with the genetic mutation is 3.77
